Parakeet loosing chest feathers

by April
(New York)

I read all the info on molting,but nothing was mentioned about chest feathers. My Parakeet has down on his chest but no real feathers, and this has been for a couple of months.He is flapping his wings in a flying fashion which I understand is part of the molting process, he eats well, sings during the day and is quiet at night so he seems to be in good health otherwise. Please advise if this is normal.
